PERFORATING VERTICAL SMART WELL COMPLETIONS USING TUBING CONVEYED PERFORATING GUN ASSEMBLIES: CASE HISTORY APPS 15 18 AUTHORS: Stuart Wood, Lachlan Comb, Mandeep Kuldeep Singh, and Joshua Lavery, Halliburton; Matthew Biddle and Paul Gregory Hyatt, DDG Operations Pty Ltd
AGENDA/INTRODUCTION BACKGROUND INFORMATION FIELD APPLICATION Challenge #1 Cable Detection Magnetic Based Locating Tool Conventional Ultrasonic Acoustic Based Locating Tool Challenge #2 Orientating Perforations Electric Line Deployment TCP Deployment Results ACKNOWLEDGEMENTS
BACKGROUND INFOMATION SMART WELL COMPLETIONS External casing fiber optic cable Distributed pressure/temperature /acoustic sensing across entire well length Allows real time monitoring of well production or injection characteristics Any damage during installation or throughout well life renders the technology unusable
BACKGROUND INFOMATION Requirement to Orientate Perforations
FIELD APPLICATION FIELD APPLICATION Shallow, Vertical Well Fiber Optic Cable outside 7in casing Requirement to perforate underbalanced without killing well over large interval Well must have completion in place prior to perforating Utilize the highest performance charges possible in 7in casing (not through tubing charges)
FIELD APPLICATION CHALLENGE #1 Locating the FO cable s azimuthal direction on the outside of the casing in a near vertical (<5 ) well with large casing (7 in. OD). CHALLENGE #2 Orientating the perforations in a near vertical (<5 ) well CHALLENGE #3 How could the above 2 operations be referenced to each other
FIELD APPLICATION CHALLENGE #1 CABLE DETECTION Magnetic Based Locating Tool Allows real time detection and orientation of perforating gun away from external metal mass SIT tests demonstrated the optic fiber clamp could be easily and reliably identified
FIELD APPLICATION CHALLENGE #1 CABLE DETECTION Conventional Ultrasonic Acoustic Based Locating Tool Existing, readily available technology Required for cement or Pipe inspection on most wells anyway SIT confirmed detection of clamp
FIELD APPLICATION CHALLENGE #2 ORIENTING PERFORATIONS Electric Line Deployment Downhole rotation of guns away from metal mass e.g. dual completion or smart completion Not possible to use in this circumstance with guns on completion
FIELD APPLICATION CHALLENGE #2 ORIENTING PERFORATIONS TCP Deployment Existing technology Wireline Gyro with stinger and UBHO sub in TCP/completion string Simply rotate completion and check gun phasing compared to cable, set packer shoot guns
RESULTS Operational Step Results Measure direction of clamp / cable from Clamp is at 258.5 UltraSonic Log Run Gyro tool to engage in UBHO sub Keyway is at 294.2 Calculate the corresponding direction of the Gun phasing is at 114.2 and 294.2 perforation phasing Re Run Gyro to confirm direction of Keyway Results repeatable within 1 Rotate completion string at surface by 60 clockwise to ensure gun string is at approx. 90 phasing to clamp Re Run Gyro to confirm direction of Keyway Keyway is at 359.8, so Gun phasing is at 179.8 and 359.8 Set completion packer Re Run Gyro to confirm direction of Keyway Confirmation of negligible UBHO/gun rotation. Drop Bar to fire guns Successful Flow to surface
